Abstract
The invention relates to an overhead power transmission line telescopic grounding wire hanging rod and a hanging method. Along with rapid development of State Grid Corporation of China, high-voltage and extra-high-voltage power transmission lines increasingly become skeleton power grids in China and provide reliable and stable power energy for the society and the masses. However, overhead lines are exposed in the wild all year around, the probability that the overhead lines are damaged by nature and external forces is high, and line defects are difficult to avoid. The overhead power transmission line telescopic grounding wire hanging rod comprises an insulating rod (1) and a tool joint (3) in composition, wherein a group of through holes are formed at the upper part of the insulating rod; telescopic control pins (2) are arranged in the through holes; the tool joint is embedded and fixedly connected inside the innermost layer of the insulating rod; a locking spring ball (4) is arranged in the tool joint; a grounding wire connection screw (5) is arranged outside the tool joint; one end of the tool joint is connected with an aluminium alloy wire chuck (7); and the aluminium alloy wire chuck is provided with a wire chuck control pin (6). The overhead power transmission line telescopic grounding wire hanging rod and the hanging method which are disclosed by the invention are applied to the overhead lines.

Background technology:
Along with developing rapidly of national grid, high pressure, extra high voltage network increasingly become China's skeleton electrical network, provide reliable and stable electric power energy for society and the people.But, overhead transmission line is exposed to field, wilderness throughout the year, and the probability destroyed by nature and external force is higher, it is difficult to avoid line defct.According to national grid state evaluation requirement, the defect processing that carries out circuit periodically or non-periodically overhauls to reach to ensure the purpose that line security runs.
500kV
Line voltage distribution grade is high, fed distance is remote, coverage is wide, and therefore, the shortening interruption maintenance time is the most necessary to greatest extent.In real work,
500kV
Overhead transmission line interruption maintenance hangs earth lead time average and exists
30
More than minute, being primarily due in presently used earth lead installation process use suspension of tossing, the accuracy that wire clamp is connected with wire is poor, and the biggest corner steel tower outboard wire hangs increasingly difficult.So, it is the most necessary for studying a kind of earth lead instrument of can the most accurately installing.
Summary of the invention:
It is an object of the invention to provide a kind of overhead transmission line telescopic earth lead hanger bar and hanging method.
Above-mentioned purpose is realized by following technical scheme:
A kind of overhead transmission line telescopic earth lead hanger bar, its composition includes: insulating bar and tool-joint, the top of described insulating bar is provided with one group of through hole, there is in described through hole extension and contraction control pin, described tool-joint is embedded to be connected with fixing in the insulating bar described in innermost layer, there is in described tool-joint locking spring ball, there is outside described tool-joint earth lead connecting screw, one end of described tool-joint is connected with aluminium alloy conductor chuck, described aluminium alloy conductor chuck has wire clamp and controls pin.
Described overhead transmission line telescopic earth lead hanger bar, described insulating bar uses
3
Save a length of
1.2m
Identical material, different-diameter insulation pipe inlays composition, and described extension and contraction control pin uses built-in spring structure.
Described overhead transmission line telescopic earth lead hanger bar, described deflation spring ball and earth lead chuck compact siro spinning technology, described earth lead connecting screw weaves earth lead with the copper of band transparent sheath and is connected.
The hanging method of described overhead transmission line telescopic earth lead hanger bar, the method comprises the steps:
Extension and contraction control pin uses the design of built-in spring, controls insulating bar distance of stretch out and draw back.Tool-joint is embedded in innermost layer insulating bar, use fixing connection, locking spring ball is positioned at tool-joint, can be with earth lead chuck compact siro spinning technology, earth lead connecting screw is for connecting the copper braiding earth lead of band transparent sheath, wire clamp controls pin can strut coverage by aluminium alloy conductor chuck, hang earth lead personnel this invention hand-held and accurately earth lead chuck can be delivered to wire hanging position, automatically spring open after aluminium alloy conductor chuck touches wire, can easily regain expansion link.
Beneficial effects of the present invention:
1.
The present invention is applicable to
500kV
And earth lead hangs during following electric pressure overhead transmission line power cut, the most right
500kV
The suspension of overhead transmission line big corner steel tower outboard wire earth lead, efficiently solves big corner steel tower outboard wire and hangs earth lead difficult problem.This telescopic earth lead hanger bar simple in construction, easy to carry, installing earth lead accurate, the feature of raising work efficiency flexibly.
What the present invention solved is that existing earth lead hangs difficulty, the problem that hookup time is longer.This telescopic earth lead hanger bar is collectively constituted by insulating bar, extension and contraction control pin, tool-joint, locking spring ball, earth lead connecting screw, wire clamp control pin, aluminium alloy conductor chuck, accurately earth lead chuck can be delivered to wire appropriate location, guarantee that earth lead is connected with the accurate of wire, reduce the time of hanging earthing conductor, improve work efficiency.
